Wilfred enlisted with the 7th Cheshire Regiment shortly after the start of the war. He served with the regiment at Gallipoli in 1916 but was repatriated to England after being wounded in the thigh, and was treated at Cardiff hospital. When fully recovered, he was transferred to the Royal Welsh Fusiliers and drafted out to France in the spring of 1917.

Wilfred was killed in action on 28 July 1917 and his death was reported in the Macclesfield Times on 31 August 1917:

THE LATE PTE W WEATHERMAN – …Pte Wilfred Weatherman, 19 Barracks Square, Macclesfield… was killed in action in France on July 28th. Twenty-three years of age, Private Weatherman was formerly employed at Mrs Leach’s dye works, and volunteered for service shortly after the outbreak of war. He enlisted in the local Territorials and went out to Suvla Bay with the battalion, being wounded in the thigh. Eventually he returned to England and underwent treatment at Cardiff Hospital. On his discharge Pte Weatherman went to a convalescent camp at Heaton Park, and was afterwards stationed on the East Coast for several months. Later he was transferred to the Royal Welsh Fusiliers and drafted out to France about three months ago. Three brothers of Private Weatherman reside in Macclesfield, one being a member of the Borough Police Force.
